1.纯水电解制氢

1. hydrogen production by pure water electrolysis

把满足要求的电解水(电阻率大于1MΩ/cm,电子或分析行业用的去离子水或二次蒸馏水皆可)送入电解槽阳极室,通电后水便立刻在阳极分解:2H2O=4H++ 2O2-,分解成的负氧离子(O2-),随即在阳极放出电子,形成氧气(O2),从阳极室排出,携带部份水进入水槽,水可循环使用,氧气从水槽上盖小孔放入大气。氢质子以水合离子(H+?XH2O)的形式,在电场力的作用下,通过SPE离子膜,到达阴极吸收电子形成氢气,从阴极室排出后,进入气水分离器,在此除去从电解槽携带出的大部分水份,含微量水份的氢气再经干燥器吸湿后,纯度便达到99.999%以上。

To meet the requirements of water electrolysis (resistivity greater than 1M /cm, deionized water or electronic analysis for the industry or two times in distilled water can be) into the anode chamber of the electrolytic bath, the water immediately after power on the anode decomposition: 2H2O=4H++ 2O2-, negative oxygen ion decomposition into (O2-), then release electrons at the anode. The formation of oxygen (O2), discharged from the anode chamber, carrying some water into the water tank, the water can be recycled, oxygen from the tank cover holes into the atmosphere. Hydrogen proton to hydrated ions (H+? XH2O) form, under the action of electric field force, through the SPE membrane, reach the cathode absorption electrons to form hydrogen, discharged from the cathode chamber, into the gas water separator, then remove most of the water carrying out from the cell, containing trace water hydrogen by the dryer after moisture absorption the purity is above 99.999%.

2.碱液电解制氢

2. hydrogen production by alkaline electrolysis

工作原理是传统隔膜碱液电解法。电解槽内的导电介质为氢氧化钾水溶液,两极室的分隔物为航天电解设备用优质隔膜,与端板合为一体的耐蚀、传质良好的格栅电极等组成电解槽。向两极施加直流电后,水分子在电解槽的两极立刻发生电化学反应,在阳极产生氧气,在阴极产生氢气。反应式如下:阳极: 2OH--2e → H2O+1/2O2↑ 阴 极: 2H2O +2e →2OH- +H2↑ 总反应式: 2H2O → 2 H2↑ +O2↑ 本仪器对压控、过压保护、流量显示、流量追踪等均实行自动控制;使输出氢气能在恒压下,根据气相色谱仪用氢气量,实现全自动调节(在产气量范围内)。

The operating principle is the traditional diaphragm electrolysis method.  The conductive medium in the electrolytic bath is potassium hydroxide aqueous solution, and the separator in the two polar chamber is an electrolytic tank composed of a high quality diaphragm, a corrosion resistant and mass transfer, a good grid electrode and a good grid electrode which are integrated with the end plate in the space electrolytic equipment. When the direct current is applied to the poles, the water molecules react immediately at the poles of the bath, generating oxygen at the anode and producing hydrogen at the cathode. The reaction equation as follows: 2OH--2e: H2O+1/2O2 = - anode cathode: 2H2O +2e 2OH- +H2, the total reaction type: 2H2O, H2 = 2 = +O2 = the instrument of pressure control, overvoltage protection, flow display, flow tracing are the implementation of automatic control; the output of hydrogen at constant pressure, according to gas chromatography with hydrogen gas the spectrometer, automatic regulation (in gas range).
